Getting back into BMX after 20 years

Hello all, Im new to the forum. Im 35 and my kids are starting to ride bikes now and I want to get a new bike to ride with them.
My local shop sells Kink and Fit bikes, and I was thinking about getting a Kink Curb as my intro bike, but the salesman is trying to get me to go for the Kink Whip instead because its full Chromo.
For that much money though I could get a WTP Arcade, which isnt full Chromo, but Im assuming has better parts. So I need advice on which way to go. Good frame, or good components?
Any advice would be greatly appreciated.

Thanks a lot. That explained a lot of stuff Ive been curious about. Im just going to go to the shop and see how much it will cost to frankenstien myself a custom. It will probably be too much, and Ill just end up getting the Whip.
